About Mark Costello

Mark Costello and his wife, Brandy, have been immersed in the real estate sector since their teenage years, gaining extensive experience across various aspects of the industry. Their diverse backgrounds have equipped them with a comprehensive understanding of homes and the intricacies of the buying and selling process.

Real estate has profoundly impacted their lives, and they are passionate about making a positive difference in the lives of their clients. As devoted parents to three boys, their family serves as their primary motivation. Their youngest son, Carter, often accompanies them, bringing an extra touch of enthusiasm to closing day.

When clients choose to work with Mark and Brandy, they receive personalized attention from the duo, rather than being handed off to a larger team. They pride themselves on being involved in every step of the transaction, ensuring a seamless experience. Additionally, they collaborate with a network of skilled professionals who share their commitment to meticulous service.

Mark's early career included work in residential and light commercial construction, where he gained hands-on experience in renovations while collaborating with various investors. Brandy, on the other hand, began her journey in the appraisal field during high school, later transitioning to become a licensed REALTOR®. Her keen eye for design and current trends allows her to help clients visualize potential in properties, regardless of their present condition. Together, they leverage their combined expertise to assist clients in renovating homes for both personal and investment purposes.

Whether clients are seasoned investors, looking to buy or sell their second home, or first-time buyers, Mark and Brandy are eager to meet them at any stage of the process. They look forward to the opportunity to work together and guide clients in making informed decisions for their families.

If you need to reach working real estate agents in Parker County, Texas, this list was built for you. Mortgage lenders prospecting for referral partners, title companies expanding their agent network, PropTech companies demoing new tools, recruiters targeting experienced agents, insurance providers, and continuing education providers all rely on targeted agent data to drive outreach that actually converts. A verified, county-level list eliminates the waste of broad state campaigns and puts your message in front of the right professionals.

This Parker County real estate agent email list includes {{AGENT_COUNT}} actively licensed agents with verified email addresses, plus {{CELL_COUNT}} agents with cell phone numbers for multichannel campaigns. Whether you are launching a cold email sequence, running a direct mail drop, or building a phone list, this data gives you a complete contact profile for every agent in the county.

Why Buy a Parker County Real Estate Agent Email List From Dr Bill

Dr Bill has been selling real estate agent lists since 2005 and has moved over 31,000 lists to marketers, lenders, recruiters, and vendors across the country. Every record is sourced directly from the Texas Real Estate Commission and other state licensing authorities, so you are not buying scraped web data or recycled contacts from a reseller. New emails are added weekly, the full list is cleaned monthly, and the entire database is refreshed bi-annually. That process backs a 96% deliverability guarantee — a standard most cheap list vendors cannot touch because they never invest in ongoing maintenance.

Discount list providers cut corners on verification and sell the same stale file for years. That approach wastes your sending reputation and your ad spend. When you buy a Parker County real estate agent email list from a source that guarantees deliverability and documents its update cycle, you protect your domain, your pipeline, and your ROI from the first send.

How to Use This Parker County Agent List

Cold email is the most efficient first use. Load the list into a dedicated cold-email platform built for outreach — Zap Contact at zapcontact.com is purpose-built for exactly this type of B2B agent campaign and pairs well with this data. You can also use the mailing addresses for direct mail, the cell numbers for SMS or call campaigns, and the agent names for LinkedIn matching to build a parallel digital audience alongside your email sequence.

The data is segmented by broker versus sales agent, so you can tailor your message accordingly — pitch brokers on tools that affect their whole office and pitch individual agents on services that help their personal production. Zip code, city, and county-level segmentation lets you slice the list however your campaign requires.

Why Parker County, Texas Agent Data Matters

Parker County includes Weatherford, Aledo, Willow Park, Springtown, and Azle — a corridor of active real estate markets west of Fort Worth with its own agent community that often gets lost inside statewide list pulls. With {{AGENT_COUNT}} licensed agents operating in this county, there is a meaningful audience worth targeting on its own terms rather than burying it inside a Dallas-Fort Worth metro blast where your message competes for attention at massive scale.

No other list vendor offers zip code-level segmentation within Parker County, which means you can isolate agents working specific communities if your product or service has a geographic fit. Local targeting at this resolution is what separates a campaign that generates callbacks from one that generates unsubscribes.
